The Schneider Electric STBEPI2145K is a comprehensive parallel interface kit designed for the Modicon STB distributed I/O solution. This kit contains everything you need to connect and control TeSys U and TeSys Quickfit motor starters. The module features 12 input channels and 8 output channels, all operating at 24V DC. With its compact form factor and robust protection features, the STBEPI2145K simplifies wiring and reduces cabinet space requirements. Additionally, the module supports both hot swapping and cold swapping, enabling maintenance without shutting down the entire system.
The Schneider Electric STBEPI2145K provides 12 digital input channels with a 24V DC nominal voltage. The input voltage limits range from 15 to 30V for a guaranteed state 1 (high) signal, and -3 to 5V for a guaranteed state 0 (low). For state 0, the current stays below 0.5mA, while state 1 requires at least 2mA. The module integrates input protection through resistor-limiting circuits. This design safeguards the module against accidental overvoltage or current surges from field sensors. Moreover, the inputs interface directly with standard 24V DC sensors without requiring additional signal conditioning.
The STBEPI2145K delivers 8 digital output channels at 24V DC. These outputs are designed to drive actuators, relays, and indicator lights directly. For overload and short-circuit events, the module integrates robust protection mechanisms. A time-lag 10A fuse on the power distribution module (PDM) provides primary power protection. The outputs also feature short-circuit protection to prevent damage from wiring faults. The module draws ≤100mA at 24V DC from the sensor bus, and ≤220mA from the actuator bus during a 150ms startup surge. When all 8 outputs are off, the actuator bus current drops to 50mA. Each active output adds 80mA to the total consumption.
The Schneider Electric STBEPI2145K works exclusively with the STBXBA3000 mounting base. For power distribution, you must use either STBPDT3100 or STBPDT3105 power distribution modules. The kit includes a terminal spring clamp connector and a terminal screw-type connector for flexible wiring options. This module also accommodates both standard NIMs (Network Interface Modules) and basic NIMs. For standard NIMs, you can configure fallback states (output behavior during communication loss). Basic NIMs default to state 0 (outputs off) during fallback.
The STBEPI2145K operates reliably across a wide temperature range from -25°C to +70°C without derating. Storage temperatures extend from -40°C to 85°C. Humidity tolerance reaches 95% at 60°C without condensation, making it suitable for demanding industrial environments. The module holds FM Class 1 Division 2, UL, and CSA certifications for hazardous locations. Vibration resistance reaches 3gn (58-150Hz) on a 35x7.5mm DIN rail, and 5gn (58-150Hz) on a 35x15mm rail. Shock resistance is 30gn for 11ms, ensuring durability during transportation and machine operation.
Four LEDs provide clear status information on the STBEPI2145K. A green RDY LED indicates the module is ready and communicating properly. A red ERR LED signals a module error for quick troubleshooting. Two green LEDs (S1 and S2) show the switch position for configuration. Additionally, four green LEDs display individual output status, giving you immediate visual feedback on output states without needing a programming terminal.

Q1: What is the primary application for the STBEPI2145K?
The Schneider Electric STBEPI2145K is specifically designed to interface with TeSys U and TeSys Quickfit motor starters in distributed I/O systems.
Q2: Can I replace this module while the system is running?
Yes. The STBEPI2145K supports hot swapping when using standard NIMs. This allows replacement without powering down the system.
Q3: What protection features does this module include?
The kit includes power protection (10A time-lag fuse), overload protection, short-circuit protection, and resistor-limited input protection.
Q4: Does the module work with any STB mounting base?
No. You must use the STBXBA3000 mounting base with the STBEPI2145K for proper compatibility.
Q5: What are the fallback options for outputs?
For basic NIMs, outputs default to state 0 during communication loss. For standard NIMs, you can configure user-defined fallback states.
